Application fled Iayj'l,

To all whom it may concern:

Be it known that I, Fame-men Hanson- MANN, a citizen of the United States,'and

a resident ofthe cilg of New York, borough of Manhattan, in e county and State of New York, have invented a new and Improved Collapsiple Tube, of which the folthe window removed;

lowing is a clear, and exact description.

This invention relates to collapsible tubes and more particularly to devices of this character which are adapted for dispensing icing for cakes and allow the same to be directed inany desired shape or form.

Of course, the invention is not limited to the contents of the tube as I ma employ the tube for containing any liqui or semiliquid of paste-like composition.

An object of the invention is to provide a collapsible dispensing tube having a window or windows which permit observation of the contents of the tube.

A further object is to provide an improved construction and arrangement of nozzle andmounting therefor which rmits the outlet to be opened or closed an which dilOtS the discharge of the contents of the tll A further object is to rovide a tube of the character "stated em ying novel details of construction which will facilitate the assemblage and the operation of the tube in dispensing its contents.

With these and vother objects in view, theinvention consists ihicertain novel features of construction and combinations and arrangement of parts which will be more fully hereinafter described and pointedout in the claims. a

In the accompanying drawings- Figure 1 is a perspective view of a tube illustrating one embodiment of my invention;

Figure 2 is tion through the center of t etube illustrated in Figure 1, the view being taken atright angles to said Figure 1;

Figure 8 is a view in transverse section on the line 8-8 of Figure 7; p

Figure 9 is a perspective view showing Figure 10 is a perspective view of the frame for holding the window in place.

Referring more particularly to Figures 1 to 5, inclusive, 1 represents an outer tube of tubular form and both the lining 2 and the tube 1 are made with registering openings 3 and flexible and bendable transparent material 4 is interposed between the tube 1 and the lining 2 and extends across the openings 3 so as to provide windows in the tube through which the contents of the tube can be observed. 7

I have illustrated the device as provided with two of these windows at op osite sides of the tribe, but it is obviousthat the invention is not limited to any particular number of such windows nor to their size, shape and location.

The upper end of the tube 1 is formed with a neck 5 .of a reduced diameter as regards the main body of the tube 1, and this neck 5 has a closed upper end 6 provided with an e e 7 or other suitable arrangement by w ich the tube may be readily suspended 'from a hook or nail when not desiredfor use.

The upper end of the lining 2 is also formed with a restricted neck portion 8' which projects into the neck 5 of tube 1. The neck 5 is externally screw-threaded, as

shown at 8 to mesh with internal screw threads in a sleeve 9. This sleeve 9 supports a discharge nozzle'lO, the latter being of any desired shape in cross section but referably provided with a screw-threaded fmner end 11 to engage a threaded opening 12 in the sleeve 9 so that various nozzles can be coupled to the sleeve in accordance with the shape desired to be imparted to the contents of the tube when discharged therefrom. 7

It will be noted that the head 6 is enlarged and ofgreater diameter than the neck 5'. This absolutelg prevents accidental removal and loss of t e sleeve 9. In constructing the device, the neck 5 is of the same diamand 2 an inner lining. This lining 2 is also eter throughout until the sleeve is positioned thereon, when the upper end of the neck can be hammered, molded or otherwise formed to give the necessary enlargement thereto.

' I have illustrated in Figures 1, 2 and 3 nozzles 10 having rectangular bores, and in Figure 6 I have illustrated a nozzle 13 having a narrow somewhat elliptical shape, but it is obvious that nozzles of any shape may be employed.

A discharge opening 14: is provided in the wall of the neck which is adapted to register with the nozzle and may be cut off when the sleeve 9 is turned on the screw-threaded neck 5 so as to move the nozzl out of register with said opening. It will thus be seen that the outlet can he effectually shut off whenever desired and can be opened by properly positioning the sleeve 9 to register the opening 14 with the nozzle 10.

The lower end of the lining 2 is formed. with a laterally projecting tongue 15 having a head 16 at its outer end, and this tongue and head project through the wall of the tube 1 and the lower end of the tube 1 extends below the lower end of the lining. The lining and the tube are open when filling the tube with its contents, after which the lower end of the tube is flattened, folded on itself, the lining or, at least, one portion of the lining being bent into said fold. and then a key 17 is clamped onto the folded end of the tube and the lining.

This key 17 shown in perspective in Figure 5, comprises a pair of members precisely alike in shape but integrally connected and having spurs 18 projected inwardly therefrom so that when these members of the key are forced against the folded lower end of the tube they will effectually clamp and hold the tube in closed formation.

The extremities of these key members conform in shape to the tongue 15 and head 16 of the lining 2 so that when they are in position they constitute a handle 19 projecting laterally from the tube so as to facilitate the turning of the key to wind the tube thereon and eject the contents of the tube through the nozzle 10.

In the modification illustrated in Figures 7, 8, 9 and 10, I show a tube 20 correspond ing to the tube 1. and instead of forming the windows 4, as shown in Figures 1 and 2, 1

simply' provide a single thickness of tube 20 'with an opening or openings 21 in the wall thereof, and cover said opening or openings with sheets of trans arent, flexible, bendable material 22 secure against the outer face of the tube by flexible bendable frames 23. In this modification I have illustrated a bail 24- located through an eye 25 at the top of the neck portion 5 of the tube as a supportmg means, but various other means may be provided for hanging or suspending the device.

While I have illustrated what I believe to be the preferred embodiment of my invention, it is obvious that various slight changes and alterations might be mad in the general form of the parts described without departing from my invention, and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. As a new article of manufacture, a collapsible dispensing tube, comprising a pair of tubes, one located within the other and having registering openings, and a transparcnt sheet located between the tubes and across the openings and constituting a transparent window through which the contents of the dispensing tube can be viewed.

2. As a new article of manufacture, a collapsible dispensing tube having a lining therein, said lining and said tube having registering openings and flexible transparent material located between the tube and its lining and constituting a window whereby the contents of the tube can be seen from the outside.

3. As a new article of manufacture, a collapsible dispensing tube having a neck at one end, said neck having an opening in its wall, a sleeve movable on said neck and having an opening adapted to register with the opening in the neck or moved to a position to close said opening, a nozzle remov ably secured in the opening of the sleeve and constituting a form or die to shape the material expressed from the tube, meansgon the end of the neckfor supporting ther tnbe, and a key secured to the end of the tube for collapsing the same.
